A bucket funnel has a funnel body which clips onto a bucket with a top flange. The funnel body has a semicircular lower edge which has about the same radius of curvature as the bucket, but only extends about halfway around. There are outer tabs with inward facing channels at the ends of the lower edge of the funnel body to clip into the flange of the bucket. There is also a spring loaded release clip at about the middle of the lower edge to clip onto the outer flange of the bucket. An inner apron extends down from the lower edge of the funnel body to form a seal against the inner wall of the bucket. An interchangeable conical nozzle attaches to the funnel body for dispensing of fluids of various viscosities, such as glue, paint or fresh concrete.
